4.5 Gallon Bladder Tank for Reverse Osmosis Systems:
The 4.5 Gallon Reverse Osmosis System Tank is the standard sized tank for most RO systems.
The RO Tank has a 1/4" NPT stainless steel connector at the top of the tank.
You can purchase replacement ball valves below. There is a 1/4" end that connects to the top of the RO tank. Purchase the BV-3890-AP ball valve if you have 3/8" tubing connected to your RO tank. Purchase the BV-1490-AP if you have 1/4" tubing connected to your RO tank.
There is a side mounted air valve for re-pressurizing the tank when needed.

This tank is the same as the American Plumber 144165 and the Pentek 144165 RO tank. It is also known as the RO-132 tank.
This RO tank has been tested and certified by NSF International under NSF/ANSI Standard 58 for material and structural integrity.
A black RO tank stand is included with the RO tank.

Reverse Osmosis System Accessories:
Use a TPG-100 Digital Tank Pressure Gauge to measure the air pressure in your Reverse Osmosis Bladder Tank. The RO Bladder Tank can lose air pressure and needs to be monitored.
Use an Inline TDS Meter to monitor the Total Dissolved Solid levels before and after your Reverse Osmosis System.
Instructions to Properly Pressurize your Reverse Osmosis Tank:
Before setting the pressure on your tank, you should empty the tank of water.
There are two nipples on the tank. The nipple on the bottom should have a blue cap on it. Remove this cap and use a bicycle pump to add pressure to the tank.
You should use a digital pressure gauge on the nipple because non-digital pressure gauges are not sensitive enough. You can purchase a digital pressure gauge here if you do not already have one
Correct pressure for your Tank:
The recommended pressure for your tank depends on the size of your tank. The most common tank size is 3.2 gallons. For these and similarly-sized tanks, you should have pressure of 8 psi when the tank is empty. If the tank is full, there should be 36 psi.
For larger tanks, such as 14 gallon, 36 gallon, 44 gallon, and 86 gallon units, the pressure will need to be greater.
